As discussed on the mailinglist [1] the tiling support is
removed from KWin. The main reasons for this step are:
* it is unmaintained
* it is a mode not used by any of the core KWin team
* original developer said at Akademy 2012 that he is not
interested in picking up the work again
* tiling has quite some bugs, e.g. multi screen not supported
* is conflicting with other concepts in KWin, e.g. activities
There is ongoing work to get tiling supported through a KWin
script, which is a preferred way as it does not influence the
existing C++ code base.

This is an issue we already had in the past with Aurorae. When
closing a window the graphics scene crashes because the deco
gets destroyed before the code in the graphics scene finished
the execution.
With the port to QML this seemed to be fixed unless as it turns
out it throws an XIO error on closing:
fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
This can be triggered using glxgears. Closing glxgears would
reliable crash Aurorae. To circumvent this issue we have to
delay the close by one event cycle using QMetaObject's
invokeMethod with a Qt::QueuedConnection.
This has also to be done in the useractions menu as the menu
is still open when the window closes causing the same problem
inside Aurorae.

we cannot fix Qt DnD crashing on client destruction (eg. also occurs with toolptips)
but we can prevent it to happen with effects by just un/mapping the input window instead
of destroying and re-creating it

as the flamewar pointed out, resetShowingDesktop invalidly keeps hidden windows
the reason is that there're several updateVisiblity calls (notably one from the compositor)
which break the showingDesktop state as a side effect (before ::manage() does it's thing)
Since they also invalidate the Withdrawn mapping state, that will fail as isManaged() test
(it's also invalidly used by the compositor to set up the decoration, isManaged() used to be
true because of the updateVisibility() call before) since the result is never Withdrawn

Upscaling windows looks really bad. If the thumbnail gets larger
than the window it's better to just use the orignal window size
and have the thumbnail rendered centered in the requested
region.

The logout effect was rather broken. First of all it was
excluded from build if OpenGL ES is present at build time. The
reason for this is that the effect did not work with GLES.
In order to fix that the vignetting is ported over to OpenGL 2
by using a dedicated shader. As well the lod based blur is
added through a dedicated shader and uses framebuffer blit to
get the current rendered buffer before rendering the logout
window into a texture.
Last but not least the isActive method was broken and is fixed
by checking whether the logout window is around.

The LanczosFilter has a FBO in screen size. When the screen
geometry changes this FBO has to be recreated. To go completely
sure the lanczos filter gets deleted on screen changes.
To achieve this the LanczosFilter is wrapped inside a
QWeakPointer so that we can track when it got deleted. This
brings an additional advantage by delaying the creation of the
shader till it is really needed, that is when for the first
time a window thumbnail with lanczos is rendered.

According to Nuno it's much better to define the animations in
a Behavior element as that is together with the element which
gets animated.
Also he recommends to not use states but just property binding
for the properties which are animated in the Behavior.
And I must admit that this produces cleaner code, though the
conditions are now scattered all over the source code and not
nicely put together in one state section. Let's just hope I got
the logic right.
Well seems like it is useful to go to a QML training, at least
it made me aware of my State definitions are not good and then
talking to Nuno and giving a try to his recommendations.

A new global method is exported to perform a remote method call
through D-Bus. The call is always performed async invoking a
callback once the call completed passing through the arguments
received from D-Bus.
Possible code looks like the following:
callDBus("org.kde.kwin", "/KWin", "org.kde.KWin", "currentDesktop", function (desktop) {
print("Current Desktop through D-Bus: ", desktop);
});

m_textureNPOT and m_limitedNPOT have not been initialized in the ctor resulting in
m_limitedNPOT being incorrectly being true sometimes for Intel drivers. For other
drivers the value had been set.
For Sandybridge Lanczos Shader is enabled, but only GLSL is working
so the ARB variant has to be disabled for Intel GPUs.
